LWAY CAR.

Application filed. November 12, 1919. Serial No. 337,415.

To all whom it may concern:

Be it known that ll, JOHN O. NEIKIRK,

a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Railway Cars, of which the following is a specification.

This invention relates to railway cars, and more particularly to doorconstructions and arrangements in connection therewith.

It is common experience among car p: erators to have difliculty inclosing floor or dump doors which at times are prevented from beingentirely closed by pieces of coal or other material becoming lodgedbetween the door edges and associated frame members of cars.

Therefore, one object of my invention is to overcome this objectionablefeature by providing such floor or dump doors with means for cuttingthrough such clogging material so that the doors may be completelyclosed with the minimum amount of effort.

Another object is to provide a door having parts adapted to reinforceassociated frame members.

Another object is to provide a novel door construction for generalservice cars adapted to meet the various requirements under serviceconditions. I

These and other objects are accomplished by means of the arrangementdisclosed on the accompanying sheet of drawings, in which-- Figure 1 isa transverse sectional view of a general service car embodying myinvention;

Figure 2 is a sectional view of my improved door construction taken inthe plane of line 2-2 of Figure 1; I

Figure 3 is a plan view of a modified form of door embodying myinvention; and

Figure 4: and Figure 5 are sectional views taken respectively along theline 4-4 and line 55.of Figure 3.

The various novel features of my invention will be ap arent from thefollowing description. and t e drawings, and will be particularlypointed out in the appended claims.

Referring to the figures of the drawings,

it will be noted that I have disclosed my invention in connection with ageneral service usual flanges 17, while overlie the edges of the door12. As mentioned hereinabove, great difficulty sometimes is encounteredin attempting to close these doors when coal or other material is wedgedin between the flanges 17 of the frame members and the edges of thedoors. To overcome this objectionable feature, I have provided a doorstructure in which the edges of the door take the formof metal anglemembers 18, the upper edges 19- which engage the flanges 17 being knifeedges, so that any coal or other material which is clogged in betweenthe edges 19 and the flanges 17 will be readily cut by the cutting edges19 which are unamociated with an grooves wherein material could collect,w ereupon the door may be moved into closed position with relativelylittle eifort. The angle members 18 of the door are connected bysuitable wood members 20, the outer one of which is inclined as at 21for engaging the under surface of a longitudinally extending side member22.

The doors 12 are supported in closed 0- sition preferably by a laterallymova le shaft 23, which is movable in a slot 24 formed in the crossframe members 15. As shown at the left hand side of Figure 1,

-.the doors 12 are supported in their upper or closed position, theshaft 23 being located under the door. The doors may be released by anoutward lateral movement of the shaft 23. When the door is held in itsclosed position by the shaft 23, the verti= cal flanges 19 of the doorangle members 18 engage the horizontal flanges 17 of the cross membersand act in a manner to reinforce the latter.

Referring particularly to Figures 3, 4i and 5, Ihave shown a floor dumpdoor made entirely of ressedsteel, the vertical side flanges 25 0 whichare provided with cutting edges 26 for cutting through clogging OFCHICAGO, ILLINOIS, ASSIGNOR T0 NATIONAL DUMP CAR 6Q, v CHICAGO,ILLINOIS, A. GORPORATION 01F lllltb material which may be caught betweensuch edges 26 and the horizontal flanges 17 of the cross frame members15. These vertical flan cs 25 also engage the horizontal flanges of t ecross members for reinforcing the- 27 which extend crosswise of the carand in the line of flow of material as 'it is being dumped from the car,thereby in nowlse acting as an obstruction, but at the same time greatlystrengthening the door. By thus corrugating the door, the usual doorbattens are eliminated.

It will be noted that the side flanges 25 of the door extend verticallyupwardly from the body of the door and that the other edges 31 of thedoor extend vertically downward from the body of the door, therebygiving great strength to the latter. outer and inner edges of the doorsare provided with flat portions 28 and 29 respectively for co-operatingwith stationary portions of the car in a manner similar to that shown inFigure 1 of the drawings.

At the inner ends of the door, demountable hinge members 30 areprovided, the hinge member 30 in each case beingmounted within thechannel portion of the corrugation, where it is out ofthe way and doesnot form an irregular surface on a used portion of the door. The type ofbin e here used forms the subject matter of art application, SerialNumber 332,638, filed October 23, 1919, and accordingly will not beclaimed herein; but it maybe stated that the hook portion of the hingesimply hooks over its supporting ivot in a manner such that the door isreadily. demountable without the use of any tools whatsoever. I

These doors are simple, strong and relatively light in construction andare adapted to meet the requirements of successful commercial operation.a

It is my intention to cover all modifications of the invention fallingwithin the spirit and scope of the following claims.

I claim:

' 1. A railway car having a dumpdoor having straight vertical flangeswith cutting edges for cutting through material lodged between suchedges and an associated frame part whereby the door may be completelyclosed.

2. A railway car having a stationary frame member, and a door having avertical flange with a cutting edge for cutting through material lodgedbetween such edge and frame member and being unassociated with amaterials collecting groove whereby the door may be completely closed.

3. A railway car having a stationary frame member with a horizontalflange, and a door having a vertical flange with a cutting The edgeengageable with said frame member closed position, said vertical flangehaving a cutting edge for cutting through any material lodged-betweensaid edge and horizontal flange whereby the door may be completelyclosed. i

5. A railway car having a dump door formed of pressed material havingstrai h't vertically arranged flanges with cuttlng edges extending abovethe adjacent body of the door for cutting through material lodgedbetween said edges and associated frame parts whereby the doormay becompletely closed.

6. A railway car having'a dump door formedof pressed material havingvertically arranged flanges with cutting edges extending above theadjacent body of the door for cutting through material lodged betweensaid edges and associated frame parts whereby the door may be completelyclosed, said door having formed therein corrugations for strengtheningthe said door.

7. A railway car having a dump door formed of pressed material havingvertically arranged flanges with cutting edges for cutting throughmaterial lodged between said edges and associated frame parts wherebythe door may be completely closed, said door I having strengtheningcorrugations formed in the line of flow of material as it is beingdumped.

8. A railway car having a dump door with vertical material cuttingflanges at its edges and with corrugations intermediate the edgesextending in the line of flow of dumpable material as it is beingdumped.

9. A- railwa car having a dump door with vertical anges at its edges andwith corrugations intermediate the edges extending in the line of flowof dumpable material. as it is bein dumped, and hinge members mounted inthe channel portions of said corrugations.

'10. A railwaycar having a dump door of pressed metal in which the sideedges are in the form of "upwardly extending vertical cutting flangesand in which the other edges are downwardly extending vertical flangeswith respect to the body of the door for strengthening purposes.

11. A raliway car having a dump door of pressed metal in which the sideedges are in the form of upwardly extending vertical e ea? cuttingflanges and in which the other edges are downwardly extending verticalflanges with respect to the body of the door, said door being providedwith corrugations for strengthening purposes.

12. A railway car having a dump door of pressed metal in which the sideedges are in the form of upwardly extending vertical cutting flanges andin which the other edges are downwardly extending vertical flanges 10Signed at Chicago, Illinois, this 5th day 15 of November, 1919.
